It started about eight thousand miles where I noticed a little hesitation. Check engine light came on and one ignition coil was replaced. Two weeks later felt hesitation again and loss of power. Check engine light came on and two ignition coils were replaced. Two weeks later felt hesitation again but check engine light will not come on. I have taken car to dealer about seven times or more to tell them what I've been experiencing with the car, but they always tell me the car is fine. I replaced all ignition coils and it ran a little better for about a week. I do have the old ignition coils. I then received a voluntary recall letter saying that my car could have defective ignition coils. Mean while my car has gotten worse. Accelerating the car is really bad. There is no power, there is a lot of knocking and pinging from the engine when I try to accelerate. Shifting is harsh and not smooth because cannot accelerate. When I let go of the gas, like when I shift gears, the car loses its speed very quickly. It feels like I'm pushing the brakes to stop the car. People driving behind me stay really far back because of how fast my car decelerates. I took my car in for the ignition coil recall but they said they are up to date, probably because I already changed them thinking it was the problem. The last time I took my car in to get it checked for the no power/performance problem, the dealer said it was fine and that it runs to design. About a week after I took it in I connected a scanner to the car and retrieved two diagnostic codes with out the check engine light being on. I think these codes could be the problem because they have to do with low voltage. I told the dealer about what happened and they told me that they know about the codes but they can't fix it if the check engine light is not on. That's what's happened so far.
